[Samba] Samba 4 LDAP NTLM password nightly injection

[Luc Lalonde]

Hello Andrew,

How would I convert the below base16 strings into raw bytes acceptable to this routine?  We presently inject the NTLM passwords directly into our LDAP database for Samba3.

Also, I can't seem to figure out the argument values for 'passdb.PDB'.  I tried 'ldb', 'samba_dsdb'.

Thanks for your help!
